An anonymous reader asks: "What cheap yet effective cooling solutions are available for servers for a small business? Keep in mind, I don't mean a small 100 employee business but rather 10 full time employees. The place is based out of an ex-residential unit, outfitted for the business. As with any small business, there wasn't any real consideration for IT needs when the place was built. The organization is getting its first real in-house server and all rooms within the unit are already in use, meaning the server must live nicely in office space, with humans, where the existing switch is. The organization follows a policy of turning off PCs and air-conditioning out of hours and in the Australian summer, the unit easily heats up past 35 degrees Celsius, exceeding the maximum operating ambient temperature for the server. Now, I can convince them of leaving the air-conditioner on, but the humans may not want the room as cool as I want it for the server and it's difficult to ensure that no one has turned it off. Are there any other cheap yet effective cooling solutions for a small business where the budget is extremely limited?"
